Your symptoms are not totally unlike mine. I only have it in one hand. I do have weakness especially when gripping. I do have tingling/itching at times. At times there is pain that I would describe as a mild ache. I had stiffness or feeling of stretching across my palm and felt the stretching up into my wrist several times. There was definite tingling and aching at night and stiffness in the mornings until I had needle aponevrotomy done.

The stiffness was relieved by the NA except some in the thumb and where the nodules are in the palm of my hand. I still feel the itching/tingling in my palm. I am now pursuing RA and expect to have that done as soon as I have the 2 weeks in a row for the treatment - July.

Maybe you have been tuned into your symptoms and are catching it at a very early stage before nodules or cords are visible. Or maybe yours are developing deeper and they don't show yet (my speculation.) You didn't say that you have nodules/bumps. Without nodules, I'm not sure how they would know where the active areas are, but if it is Dups and they can locate the active areas, you may be getting it early when RA is supposed to be most effective.

It is weird and everybody's is a little different. Are symptoms in each of your hands exactly the same, or is each hand different?

I think a second opinion would be a very good idea. Look at the clinics/practitioners who do needle aponevrotomy/NA. Are there any in your area? No matter where you live in the US, you are likely to have to travel, but there are some scattered up and down the East Coast.
You didn't describe any contracture, so NA wouldn't be a procedure that would address only nodules and lumps. However, the docs who do NA are knowledgeable about Dups and could surely give you a clear diagnosis. I am educating my GP, dermatologist, physical therapist, friends and even strangers in my town, because even those trained in the medical field know what it is but to wait until you hand is deformed and then have full surgery. My GP and dermatologist know differently now and were very pleased to know about what NA had done for me. If I get any contracture again, I'll be back getting NA. I won't even wait as long as I did before. Contracture only gets worse. It won't get better on its own.
Radiation therapy/RT is currently the only thing that will stop the progression. If you don't have contracture yet, it would be good because RT is most effective with early stages of Dups. Seems like I have seen young age as a factor they consider. so they might not want to do radiation. It's worth researching or asking about though.
Keep us posted on what you find out. We have a consortium of information gatherers on this website. Your input will help us all. None of us wants to be in this "elite" club, but we all are in it together anyway.
Good luck!

I have a feeling this is dups its just manifesting in a different way. I work in the health care field as a nurse so I have an unlimited supply of doctors and medical professionals. I've been told that the hospital I work for has a very good hand surgeon so I'm going to talk with him and see what he knows. Until then I'm going to continue to search the internet for more info. Thanks for your input I really appreciate it!
